A piece of columbite–tantalite, size 6.0 × 2.5 × 2.1 cm
Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is tantalite.[1]
Tantalum from coltan is used to manufacture tantalum capacitors which are used for mobile phones, personal computers, automotive electronics, and cameras.[2] Coltan mining[3][4] is widespread in the Democratic Republic of the Congo.[5][6][7]
